I'm an acolyte of the J programming language, attracted to SO by the set of open questions on that topic. I'm also looking forward to the release of Perl6, if and when that happens.
Because, in general, I'm interested in languages which provide abstractions that permit me to express myself briefly (something I have a hard time doing in English).
In hindsight, I realize my avatar lends itself to an, ah, interesting, interpretation as an acronym. C'est le vie.
